Overall, 11 children in England are listed as having a BMI of 40 or more in 2014/15, with a total of 475 with a BMI of 35 or more who could potentially be morbidly obese. All of these children were in year six and secondary school.

The child with the highest BMI listed in the National Child Measurement Programme data had a BMI of 41.2 and weighed 15.8 stone.

Among those with a BMI of 35 or more, the heaviest child listed weighed 16.5 stone, although they had a BMI of 37. Overall five children are listed as weighing 16 stone or more.

Around a third of the children in year six measured were either overweight or obese.

The year six pupil identified as Britain’s fattest child lives in Birmingham and was weighed as part of the National Child Measurement Programme. He weighed 16 stone 2lbs.

In contrast, the average weight of a British man is 12 stone 6lbs, meaning the obese child weighs far more than a grown adult.
